Book Excerpt: 1988-1993 Ford Fuel Injection and Electronic Engine Control... DIAGNOSIS AND TROUBLESHOOTING

INTRODUCTION In this chapter you'll see the diagnostic and troubleshooting procedures that apply to fuel-injection and engine-control systems in Ford cars and trucks, both EEC and MECS. Troubleshooting and diagnosis is the most important part of service today. In the early days of fuel injection, a mechanic (and I use the word "mechanic" instead of "technician" advisedly) would wet his finger and prescribe, "You need a new control module." That didn't cut it then, and it won't cut it now. This chapter will guide you to the source of problems. Section 2. Diagnosis and Troubleshooting Basics, gives you some troubleshooting tips and general information you should know before beginning. Section 3. Diagnostic Routines, gives you the specific troubleshooting steps. Later sections expand on the basic procedures. In all cases, the results of your troubleshooting will indicate specific components that need further testing or replacement. Look for this information in Chapter 11. If you're an owner, troubleshooting your own car, you'll need to recognize there's a limit to how far you can "wade into this pool". But you'll be way ahead of those who have said to me, "When I raise the hood on these fuel-injected cars, I'm afraid to touch anything." If you're servicing professionally, you have more tools and you can "wade in farther". I think you'll be pleasantly surprised how much you can find out using this book. By this point in this book, you should know:

• Fundamentals - what the system is supposed to do
• Operation of the sensors, the control module, the actuators and systems
• Strategies and how the control system deals with various operating conditions
• The difference between Ford EEC systems and Ford MEC systems

If you've turned to this chapter without going through the previous chapters, you're going to be troubleshooting by the numbers with little understanding of what you are doing. For example, do you know what the BOO switch is? (If you don't, look it up, using the Index.) You will use the BOO switch in troubleshooting. Today's engine controls are too complicated and too interrelated to service by the numbers. Believe me, you can't afford the time or the dollars to try the old routine of "substitute a known good part". When you try that, you're flying blind. When you finish these chapters, you'll know how to deal with diagnostics and troubleshooting and with the real problems. You'll know how to:

• Perform specific diagnostic checks to narrow the list of tests you will make for specific complaints
• Run a series of general tests that use the control module to lead you to specific service procedures
